John,
Please understand that I am in no way attempting to take away from what you've done. It can be tweaked though and I'm willing to help.
Very simple design:
Front of shirt says: "Support your Local Hookers" small print bold/font
Back of shirt has the sb logo same as the automobile stickers. Humor and you deliver your message in one color ink.
Or you could do a picture of a guy hooked up to a fish on the back.
The design shown:
John the design you show looks very busy and Im getting the idea that the main focus are three dif. things but they realy dont all play well together. 1. the sb logo. 2. the lures, looks great! but as was mentioned maybe a bit much I mean I love it, but not tied together with 1 & 3. Section three looks like it was tacked on as after thought. Again Im not attacking your work just giving my opinion. If anything I'm willing to help you work on this
Suggestions for the current design would be to increase the font size of the logo name on the back, and remove the sponsor names from the back of the shirt. This makes section 1 and 2 place a little nicer together.
Take the sponsors names, every sponsor: Have them run listed horizontally but in clear text on the sleeves of the T's.
Or have the art work on the front of the shirt, and the sb logo, same as the stickers on the back of the shirt with a listing of the sponsors on the back of the shirt. This would make soo much more sense with mock ups. If I have time today I'll hop on it.
